Holographic Dark Matter and Higgs

Abstract

We identify possible dark matter candidates within the class of strongly interacting models where electroweak symmetry breaking is triggered by a light composite Higgs boson. In these models, the Higgs boson emerges as a Holographic pseudo-goldstone boson, while dark matter can be identified as a fermionic composite state X^0, which is made stable through a conserved (``dark'') quantum number. An effective lagrangian description of both the Higgs and dark matter is proposed, that includes higher-dimensional operators suppressed by an scale Λ_i. These operators will induce deviations from the standard Higgs properties that could be meassured at future colliders (LHC,ILC), and thus provide information on the dark matter scale. The dark matter X^0, is expected to have a mass of order O(TeV), which is in agreement with the values extracted from the cosmological bounds and the experimental searches for dark matter.
